audiovis.py plays audio or visual stimuli listed in csv files passed as command line arguments (several csv files can be listed: they will simply be merged)
Each csv file must contain 3 columns:
- col1 contains onset times in milliseconds, from the start of the experiment
- col2 contains a label for the stimulus type: currently the program recognizes 'sound', 'picture', 'text' or 'rsvp'
- the content of col3 depends on the stimulus type. It must be a filename in the case of 'sound' or 'picture', or a string to be displayed in case of 'text' or 'rsvp'
Try:
python audiovis.py sounds/list1.csv pictures/list1.csv speech/list1.csv
and
python audiovis.py rsvp/list1.csv sounds/list1.csv
Note: you can always press Esc to interrupt the script.
To get the list of options:
python audiovis.py -h
For example, it is possible to display a picture, e.g. containing instructions, using the --splash option. The computer will display this picture and then wait for the participant to press the spacebar to start the experiment.
python audiovis.py --splash instructions.jpg --text-font TITUSCBZ.TTF --background-color 127 127 127 -- rsvp/list1.csv sounds/list1.csv
or
python audiovis.py --splash instructions.jpg rsvp/list1.csv sounds/list1.csv
and change the font, or the background color (not working so well now)
